Abstract: Disclosed are a light irradiating device for enhancing cell-mediated immunity and a method using the same. The light irradiating device generates a radiation with a specific peak wavelength at 610±20 nm or 710±30 nm which activates the structure of proteins involved in the activation of T lymphocytes responsible for cell-mediated immunity thus effecting immunopotentiation.
Abstract: A backlight unit with a health-care function is disclosed. The backlight unit includes: a light source including a plurality of light-emitting diodes (LEDs), at least some of the plurality of LEDs radiating light having a wavelength beneficial to the human body; and an optical output unit outputting the light radiated from the light source to a liquid crystal panel. By using a monitor or mobile phone adopting the backlight unit, immunity is improved.
